Matching Weaponized Math with Ballistic Software

I just finished up a Treadproof class with Frank and Marc (I highly recommend it) where we did Weaponized Math out to 675 yards. I am having a problem getting any of my ballistic solvers to match my dope that we gathered. I am using Strelok, AB with a Kestrel, and JBM. I have my 600 yard dope spot on. 200-500 is only .1 to .2 off which isn't necessarily much but I would like to know if it can be brought to being exact. So for the other part of my data, 650 and 675 is .2 mils off of my actual used dope. I went ahead and filled out the rest of the sheets try dope and found my software to be back within .1 to spot on. Now is this a case of only getting a chance to use this to 675? Do I need to take this out to 1000 to clean up my data?

You don't say which direction you are off, if it is all high or low or a mix, 0.1 mils is typically a ~25 fps tweak for truing.

Much like validating your inputs with your app of choice, providing ALL of the info when asking a highly technical and nuanced question will give a better answer. The devil (and answer) is in the details.

    I would say if you can get data out to 800yd then do it and hack your solver as Frank talked about in class to a solution. Otherwise, you may be able to use 400/600 data to hack your solver. If you use the 400/600 method, know that if you go further out, you may encounter more error than if you use the 600/800 method.
